a pipi monster is a genetically engineered monster that is white and is shaped somewhat like an onion. a pipi monster is born with hepatitis C. through out its life it is only 1 foot tall when its in normal stage, but it can learn to shrink to about an inch or grow to about 200 feet, pipi monsters are feisty but love their owners if raised right. the are nocturnal creatures and can be thought to fly, burn down house, turn its arms into devices and spread havoc. i am one of the few to own a pipi monster. :) i hope now u know about the pipi monsters.
i love my pipi monster named pipi'rzz
